Abstract
The present disclosure provides tissue webs with improved durability produced by rewetting a dried tissue web, pressing the rewetted web and drying the web for a second time. This improved durability is manifested by a high cross-machine direction (CD) slope.
Claims
exact text as granted — not AI-modifiedWe claim:
1. A tissue web having a CD tensile of less than about 1,500 grams per 3 inches, a CD stretch greater than about 12 percent and a CD slope greater than about 9,000 grams per 3 inches.
2. The tissue of claim 1 wherein the CD tensile is from about 1,000 to about 1,300 grams per 3 inches.
3. The tissue of claim 1 wherein the CD stretch is greater than about 15 percent.
4. The tissue of claim 1 wherein the CD stretch is from about 12 to about 20 percent.
5. The tissue of claim 1 wherein the CD slope is from about 11,000 to about 15,000 grams per 3 inches.
6. The tissue of claim 1 wherein the CD tensile is from about 800 to about 1,500 grams per 3 inches and the CD slope is from about 9,000 to about 15,000 grams per 3 inches.
7. The tissue of claim 1 wherein the web is a throughdried web.
8. The tissue of claim 1 wherein the web is an uncreped throughdried web.
9. A tissue web having a ratio of CD slope to CD tensile greater than about 10 and CD Stretch greater than about 10 percent.
10. The tissue web of claim 9 having a CD Stretch greater than about 12 percent.
11. The tissue of claim 9 wherein the CD stretch is greater than about 15 percent.
12. The tissue of claim 9 wherein the CD tensile is from about 1,000 to about 1,300 grams per 3 inches.
13. The tissue of claim 9 wherein the CD stretch is from about 10 to about 20 percent.
14. The tissue of claim 9 wherein the CD slope is from about 11,000 to about 15,000 grams per 3 inches.
15. The tissue of claim 9 wherein the CD tensile is from about 1,000 to about 1,500 grams per 3 inches and the CD slope is from about 10,000 to about 15,000 grams per 3 inches.Cited by (0)
